Sentry Crash Report:

Description Tyler Scott 2015-10-29 19:53:43 UTC 
Application: plasmashell (5.4.2)

Qt Version: 5.4.2
Operating System: Linux 4.2.0-16-generic x86_64
Distribution: Ubuntu 15.10

-- Information about the crash:
This bug is likely related to 349677 but the crash reporting assistant does nothing when I click suggest as related report. (A problem unrelated to this issue)

- What I was doing when the application crashed:

Opening the start menu and searching.

- Unusual behavior I noticed:

My task bar shows programs that don't exist and when clicking on them, will usually bring up an unrelated window, almost as if what is rendered and what is there are different.

The crash can be reproduced every time.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".

This is crashing in your graphic driver which we can't do much about.

Please upgrade/downgrade your version of mesa. See information (including a workaround) in the linked report.
